Thank for the reply Les.
I think that the ret will look and work out similar to the Burris BDC ret on full mag from what I can find out. The Burris rets work out roughly on a .177 on full mag at approx. 0.6 MD,1.2 MD and 2.5 MD which equates on a 30 yard zero to 40 50 and 60 yards depending on mounts, pellet etc.

They do look like a good alternative to the Burris scopes, with more spec for the money and an easier PX change on the fixed lens models.

Please keep us informed how you get on with these.

Thanks,
Dean.
